Extremely doubtful it will fit an XI or RHD. Its a squeeze to fit as is. Also you should not have to remove engine to install. We suggest subframe removal for ANY turbocharger swap, stock, upgraded, anything. The job can not really be done properly leaving it in place let alone someone trying to do it their driveway. For this kit it will need to be installed by a qualified technician. This is not a project you want to do in your garage or driveway. With that said we are taking every effort to make sure it installs as easy as possible.
